Dear Paul, Thanks for you reply, May I have those optimization knobs for virtual-template and throttles? Maybe looking into your configurations help me in this field. I will look for the service provider image too. Thanks

For this application, you may wish to consider the service provider images. The latest 15.x(S) image works, as it is the derivative of what was formerly the service-provider oriented 12.2(SRx) images.
However, it's unlikely to drop steady state CPU, but it may contain some optimizations for concurrent PPP (re)negotiations on the G2 platform during session recovery.
PPPoE will generally handle more users on ethernet as it is easier to push packets on when not dealing with the ATM encapsulations, but to what extent this holds true on the 7200, I can't tell you for sure.
I'd also read the broadband aggregation guide under the IOS documentation on cisco.com, and tune all the knobs that may help you, there are some pointers on what items on virtual-templates are punitive in performance, other optional items such as disabling SNMP counters on virtual access interfaces to reduce cpu usage, and other items that may help little by little. There are also various knobs to throttle PPPoE renegotiation rates during recovery.
I wish you luck (and consider getting another and/or bigger router to split the load).

Which software you used before for them?
wrote: 6000 PPP users on a NPE-G2 is way too much imho. Currently we do no more than 3000 users on a NPE-G2 with PPPoA. (Max cpu 50%). 5 years ago, we did about 5000 users on a NPE-G2, but as traffic ratio's grow each year the maximum users a NPE-G2 can handle will drop each year. Don't forget an NPE-G2 is a software based plaform, so traffic forwarding is done in software CPU.
